3 Claims.

This invention is directed to a method of making and the construction ofa hose or hose section of the type requiring flexibility, light weight,and sturdiness in use.

The primary object of the present invention is the provision of a hosesection, designed to be spliced to or with similar or like sections toform a hose of the desired length, with each such section, whenmechanically complete in hose form, being bodily dipped into a vat orother container in which there is a sufiicient quantity of acementitious and sealing composition in liquid form to completely coverthe section, the dipping operation being perfected with a View ofcoating the inner and outer surfaces of the section with a more or lesseven, smooth, and relatively thin coating of the composition to insurean effective sealing and bonding function of the parts of the section.

A further object of the invention is the provision more particularly ofa hose section of a predetermined length constructed for convenient andeffective splicing with other similar sections, to form a hose of anydesired length, with the material employed, the manner of its assembly,and the treatment following assembly, serving to form a hose of desiredand requisite flexibility.

An essential characteristic of the improved hose section is theutilization of fabric or like material formed or arranged in tubularform, and preferably provided with means for preventing collapse of thesection, with such means providing a more or less accordion-form forflexibility and bending in use and application, the material andelements of the section being responsive to sealing and bonding insubsequent treatment to provide strength and prevent leakage.

Another important characteristic of the improved hose section is thesealing and bonding of the section parts by dipping the structurallycomplete section into a vat of an appropriate cementitious and sealingcompound to insure the application of a bonding and sealing applicationto the hose section, with the clipping being repeated, or otherwisecarried out, to insure that the coating, when finally dried, shall be inthe form of an even, relatively thin, and equally distributed coatingfor the most efiective sealing and bonding.

Another important characteristic of the improved hose section is itscapability and formation to permit its effective splicing with similaror other hose sections to provide a hose of any desired length, thesplicing formation and operation being such as to insure a strong,sealed, and direct junction between the sections, in a simple,economical, and rapid operation.

The invention, in illustration of the method steps and of the mechanicalconstruction, is illustrated in the accompanying drawings, in which:

In the form of hose section shown in Figs. 1 to 9, inclusive, but whichis not to be understood as the preferred form, a reinforce l, preferablyin the form ofa wire iength, is wound spirally on a mandrel 2 of 3:, SEEand length to form a hose section of the desired length and diameter. Alayer of appropriate material, preferably somewhat porous fabric, 3, iswrapped over the rein force 5 on the mandrel, the meeting edges of thelayer 3 being lapped and secured, as by pinning or the use of acementitioiil aridsealing mate'- rial, as liquid rubber dispersion, toform an effctive bond and seal. 7 g V d A binding length, as arelatively narrow tape or cord-like strip 4 is then wound tightly overthe fabric body 3, and directly overlying the wire eeny lui qn pf ihev ei The t is a under sufiici'ent teiisi n' m'or'e'or less con thewire, ascle'arly I l in Fig. l, the body ve'r the wire length for he outer edgeof such or less widely from I ide spaces 5, which tobe referred to. pa 4binds the body ut the wire.

"B'yconfining the"space I y e' as indicated at i e'lowerend ofthe v'r- 6, by theapplication of the tape 4, the material of the coating is permitted tofill the space 6- and encase the reinforce l, to thereby bind thereinforce and body 3 and further provide for a more complete coplanarrelation of the por-' tions of the body 3 between the convolutions of'the reinforce.

The present invention is directed more particularly to the provision ofa relatively short length hose section, and obviously the sections mustbe adapted for splicing end to end for forming into hose of desiredlength. To provide for this result the formed sections, completed asdescribed, are formed for interfittin g, as at T, Fig. 3, and the formedends are coated with a relatively Heavy layer of cementitious sealingmaterial, as rubber or plastic dispersion. The sections are then forcedtightly together and by reason of the nature of the coating will befound to adhere with aconsiderable resistance to separation. A bindingtape 8 is wrapped around the joint for two or more turns, being drawntightly in place. The material of the tape 8 is of more or less porousfabric material, and in the wrappings willtake up the 'cementitious andsealing Tiriat'erial from the heavy layer at the joint. The "fabricofthe wrapping will be, by this absorption, completely sealed andcemented in place, completing the splice with very material resisttoseparation or other inherent weakness. If desired, and as preferred thematerial may "then be cur'ed in any conventional manner to furtherinsure the integrity o f 'the splice. The dispersion applied at thejoint will naturally, by reason of its nature and similarity to thedispersion used in coating the interior and jxter'iorof the section,combine with such coatin'g, iri'ak'ir'rg a 'fcbinplet'ely "homogeneousjunction of the full or "substantially full strength of the section"verse, -so that the hose, 'made up of any "desired n ine rorsecmonspliced by the de-' scribed 'rr'i'eth'o'd, present a substantiallyintegral uniform structure, without inhe'rent weakfifi a anypgint-'Inithe splicing of the joints the reinforce I may be fdis'rgarde d, andthe respective sections 'thereof need fnot be connected, as such is uhriecessary, 'as the pri'm'arypurpos'e of the reinforce i's to'pr'even'tcollapse ofa section, and efiectiv'ely carries tut this purpose withnecessity of interconnection in "spuemg the sections.

Thefiinproved-hose sections readily lend themsielves to {the-formationof branch type or Y-type hoses'ections for a p a rtioular use andpurpose. In .5 the-hese section is cut out 'to receive a b an'ehfseotion9, which may be individually in Yup as-is 'the 'ma-in s'ection. The mainand H sections are formed for iii't'er'fitting and communication by apropriate cutting, and a union is effected "and a's'e'ali'ng junctionprovided in the manner 'ties'c'ribed in connection with the splicing ofthe sections. The Y-type section, sh wn in "Fig. 6 is constructed of twobranches "ID and H fitted ai'id s'ecured to the "end of the 'inainsection, the formation and method em 'ployed being substantially similarto that described in the pi'viotisly "indicated splicing Step.

Figs/1 0, r1 and 12 'sh'o'wa somewhat different m moir of making aese'section according to this invention. In this type an appropriatelength'of fabric m is rormea imp ahollovv tube-like body f3,withthelapped'-edgs secured, as by 'the use of rubberorplasticdispersion. Rings M of metal or other material of requisite strength,are t hen inserted in the body I3. The rings are "Of an externaldiameter somewhat greater than the internal diameter of the body, sothat it is necessary to distend or spread the body l3 to permit placingof the rings. If desired, the exterior of the body it may be marked, asat 15, to indicate the desired spacing of the rings, and the latter mayvary in number and spacing in accordance with the requirements of thedesired flexibility of the section.

After the rings It are positioned, the dipping step described inconnection with the first form is carried out, and as indicated at 16 inFigure 12, the coating material will more or less encase the rings, andsecurely bond the rings and fabric. The ends of the fabric l2 are turnedover the end rings, as at H.

The length of hose section produced in either form is predetermined inorder that it may be conveniently handled, constructed, dipped andcompleted. f'he facility with which such sections may be spliced forforming any hose length provides a real advantage in the relativelyshort hose sections, both for construction, ease of handling,transportation, and ability to make up a short length or a long lengthhose as may be required at the time.

Having described the constructions of the hose sections as using wire,fabric, and rubber or plastic dispersion, it will be neverthelessunderstood that any and all materials which fulfill the requirements ofthis use and function are contemplated as within the spirit of thepresent invention.

A particular means and method of providing hose sections for ready andconvenient connection, one with another, or for providing a hose sectionshown in Figures 1 to 9 inclusive, for terminal connection with anyshape or size of fitting to which the hose is to be connected is shownin Figures 15 to 19 inclusive and forms an important object of thepresent invention.

In carrying out the method and providing the apparatus for thisconnection, the hose section proper, indicated at 22 in Figures 13 and14., is, after an incomplete series of dipping steps as previouslydescribed, terminally provided with a connection forming plug 23,preferably but not necessarily of polished metal in solid or hollowform. The plug is formed at one end, as at 24, to fit more or lesssnugly within the end of the formed but incompletely dipped hose section22. The remaining length 25 of the plug extends beyond the end of thehose section 22, and it is this length 25 which provides the connectionor cup end of the hose section. This length 25 of the plug, as willlater appear, is to be formed in accordance with the form of theconnection desired. However, regardless of the form of section 25 of theplug, the connecting cup proper of the hose section is formed in thefollowing manner. After the plug is in position in the end of the hosesection, successive layers of fabric material 25, corresponding to thefabric used in the hose section, are tightly wrapped over the end of thehose section in line with the inserted portion 24 of the plug and overthe extended portion 25 of the plug, tightly fitting and snuglyconforming to the surface formation of the portion 25 of the plug. Eachlayer of fabric 26 is heavily impregnated with rubber dispersion orother plastic or cementitious material, as in the hose sectionformation, and after such, is more or less dried, the plug is withdrawn,and the additional dipping steps of the hose section, with its now addedand practically integral terminal connection or cup section 21, arecontinued to bring the hose section and its cup connector to finishedcondition. The cup connection will thus be fixedly and inseparablyunited with and form in effect an integral part of the hose sectionproper, and after proper dipping, can not be readily distinguished information from the hose section.

Of course, that section of the connection which is formed over theextended portion 25 of the plug is the section of the complete unitwhich provides for the connection of one hose section with another informing different hose lengths, or in providing for the connection of aterminal hose length to a fixture of any type, and obviously, thissection 25 of the plug may be in any reasonable form or size.

For example, if the connection is made for joining hose sections into aparticular hose length, the length 25 of the plug may be exteriorlyformed as a somewhat loose replica of the exterior form of the hosesection proper. This is shown in Figure 14, and when the plug has beenwithdrawn, of course by an unscrewing movement, the cup extension may bereadily screwed onto the normal end of another hose section to form anefficient and practically non-leaking connection between the sections.

If the cup connection is to be made for joining a section or hose lengthto a fitting or machine fixture, the section 25 of the plug may beappropriately formed to fit such part. Thus, such plug part 25 and theresulting hose end formation 2'! may be square in cross section, as inFigure 18, triangular as in Figure 19, or round, with such portion ofeither greater or smaller diameter than that of the body of the hosesection proper, such being shown in Figures 16 and 15, respectively.

The sole requisite is the proper sizing and forming of the plug section25, for, after applying the fabric sections 26 and finally dipping thesection, the cup connection will be found to maintain its shape with allrequisite rigidity when free and yet sufficiently yielding to permit itbeing clamped on a fitting if such be necessary or desired.

It is desirable that the length 25 of the plug be of somewhat greaterlength than that of the completed cup connection 26, to provide anuncovered end of such plug for convenience in withdrawing such plug, asat 28.
